Qualitative relationships between two variables

Front

What is a qualitative relationship between two variables?

Back

A qualitative relationship describes how one variable affects another without using numerical values, often represented through graphs or descriptive terms.

Front

What does a graph with a definite change in direction indicate?

Back

It indicates that the relationship between the two variables is changing, which can suggest acceleration, deceleration, or a change in motion.

Front

How can you determine the greatest speed on a graph?

Back

The greatest speed is shown by the steepest slope on the graph, indicating the fastest change in distance over time.

Front

What does a horizontal line on a distance-time graph represent?

Back

A horizontal line indicates that the object is stationary, meaning there is no change in distance over time.

Front

What does a constant speed look like on a graph?

Back

Constant speed is represented by a straight line with a consistent slope, indicating equal distance covered in equal time intervals.

Front

How can you identify when a car is parked on a gasoline level graph?

Back

The interval where the gasoline level remains constant over time indicates that the car is parked and not consuming fuel.

Front

What does the slope of a graph represent?

Back

The slope of a graph represents the rate of change between the two variables, such as speed in a distance-time graph.

Front

What is the significance of labeling axes on a graph?

Back

Labeling axes is crucial as it provides context for the data being represented, allowing for accurate interpretation of the graph.

Front

What does an upward slope on a distance-time graph indicate?

Back

An upward slope indicates that the object is moving away from the starting point, showing an increase in distance over time.

Front

What does a downward slope on a distance-time graph indicate?

Back

A downward slope indicates that the object is moving back towards the starting point, showing a decrease in distance over time.
